Eyelash Extension Adhesives: Everything You Need To Know

Eyelash Extension Adhesives: Everything You Need To Know

Eyelash extension adhesives are a key component in the process of applying eyelash extensions. They are specially formulated to bond the synthetic lash extensions to natural lashes securely and safely, usually lasting between 4-6 weeks.

 How to choose the best adhesive for your eyelash extension treatment?

When selecting an adhesive, it is important to make sure it is medical grade and of high quality to avoid any potential irritation or damage to eyes and skin. It is also important to consider the drying time of the adhesive, as this will determine the amount of time you have to position the lash extensions accurately. Eyelash extension adhesives come in two types: latex-based and latex-free. Latex-based adhesives tend to have a stronger hold and a faster drying time, while latex-free adhesives are better for those with sensitivities.

 What is the difference between lash glue and lash adhesive?

Lash glue and lash adhesive are both used to apply false eyelashes and create a secure bond that will last throughout the day. The main difference is that lash glue is typically latex-based and lash adhesive is often a form of medical-grade adhesive. Lash glue is generally easier to remove, but lash adhesive tends to provide a stronger bond and hold for longer periods of time. Both types of adhesives should be used with caution, as they can cause irritation to eyes and skin if not used properly.

 Is lash extension adhesive safe?

Lash extension adhesive is typically safe when applied and used properly. However, it is important to take safety precautions when using lash extension adhesive, such as using a lash glue that is specifically designed for the purpose, following the manufacturer’s instructions, and avoiding contact with the eyes. Additionally, it is important to make sure to use a lash adhesive that is safe for sensitive skin and to patch test any new product before use.

What ingredients are inside of lash extension adhesive?

Eyelash extension adhesives contain Cyanoacrylate combination of these two ingredients. Cyanoacrylate is a type of plastic adhesive that is often used for medical and cosmetic applications due to its strong bonding properties and flexibility. Additionally, many eyelash extension adhesives may contain ingredients such as water, glycerin, and preservatives to increase the shelf life of the product.

Ethyl cyanoacrylate

Ethyl cyanoacrylate is a type of fast-acting adhesive that is used for bonding a variety of materials. It's also known as super glue or instant adhesive. It creates a strong bond and is easy to use, but it needs to be used carefully as it can cause skin and eye irritation.

How Temperature Affects Eyelash Extension Adhesives?

Temperature can have a relatively large effect on eyelash extension adhesives. The ideal temperature for eyelash extension adhesives is between 20-25°C, and the ideal humidity should be between 40-50%. If the temperature is too cold, the adhesive may become too thick and difficult to work with. If the temperature is too hot, the adhesive may become too thin and may not be able to hold the extensions securely. It is important to keep the temperature and humidity in the workspace at the ideal levels to ensure that the adhesive works properly.

Keep in mind working with lash adhesives with a wide humidity and temperature range allows room to perform your lash services in the event your service location temperatures and humidity fluctuate and you are not able to achieve the industry recommended humidity and temperature levels.


Humidity is your best friend when applying eyelash extensions mainly because the ingredients inside eyelash extension adhesives are effected by moisture. High humidity can cause the eyelash adhesive to become too runny, resulting in lash extensions that don't adhere properly and lead to poor lash retention. Low humidity, on the other hand, can cause the adhesive to become too thick and lead to clumping of the adhesive on the lashes. When these levels fluctuate it can slow you down in the process of lashing adding to the appointment time. 

My (#1 Pick) for a Wide Humidity and Temperature Range 

When you begin searching for a lash extension adhesive do not consider its drying time first instead ensure its temperature and humidity ranges in the event your location of servicing changes. You want to use an adhesive that can perform at its best no matter what the conditions are. In addition consider the seasonal changes.


Can you use this adhesive all year around or do you have to swap it out during the winter time where humidity drops significantly. Most importantly changing adhesive requires you to perform patch test to ensure your clients do not have any negative reactions. Be sure when you change your adhesive you test before you commit. Having a go to lash adhesive that you don't have to constantly change for each client is helpful and cost efficient.

What is the difference between drying and curing adhesive?

Drying Time is often miss-understood when applying lash extension for the first time. To simplify lash adhesive drying time is the time it takes for lash extension adhesive to activate the moment it comes in contact with a surface. That surface can include; glue rings, the activity of swiping excess off on tape, and eye patches. Once it touches a surface before the natural lash it will not adhere properly cause you to naturally want to dip and add adhesive again to the extension. Instead go straight from lash adhesive to the natural lash to ensure a proper placement and attachment. 

Curing for lash adhesive is the process of allowing the adhesive to set and harden in order to create a secure bond between the lashes and the wearer's natural lashes. During the curing process, the adhesive is exposed to moisture in air where it begins to dry and form a strong bond. This usually takes between 8-12 hours, depending on the type of adhesive used. After the curing process is complete, the lashes should remain in place and be comfortable to wear.

However there are ways to speed up the curing process after eyelash extension application. Those activities can be the use of super bonder solutions or nano misters. Be very careful using nano misters as you can easy flash cure or shock cure the lash extension bond and cause the extensions to turn white and crusty weakening the bond.

How to store lash adhesives or glue?

Lash adhesives and glue should be stored in a cool, dark place and away from direct sunlight. Keep the adhesive or glue in its original container and make sure it is tightly sealed to prevent it from drying out. If you have multiple types of glue, label and store each one separately. Additionally, you may want to store the glue in an airtight container to keep it from getting contaminated.

1. Never place Lash extension adhesives in a freezer as the temperature conditions are too cold. If you want to store inside of a cool location opt for a wine cooler temperatures for a wine cooler are warmer than freezers.

2. Store your adhesive in a stand up position to ensure the nozzle is clear and glue doesn't run to the top of the cap causing the nozzle to stick. You will not be able to remove the top and will need to throw the bottle out.

3. Place in an airtight container. The less air the ingredients are exposed to the longer the adhesive remains fresh. Air holds moisture the more air the faster the glue starts to cure naturally.

When selecting a lash extension adhesive you want to select the best adhesive to ensure long lasting lash retention the longer the clients lash extensions last on the set the happier they are. 

Your adhesive is your best friend it doesn't take long to adjust to a lash adhesive the more you use and try on different customers you will begin to see is consistency in retention. 

As you perform lash extension services you can easily identify if the glue is not adhering properly if its been out to long and its time to change your dot. These are all good ways to indicate if your adhesive is performing properly and you are working at a good pace that is realistic for you and comfortable.
